An housing I! and each cylinder 29-has a piston 30 50 elongated casing i has one end portion formed therein, (see Figure 7) which is connected to the with a tubular part 8 which is firmly fastened arm 2| by a link 3| and each piston has a port to the outer end of each housing 2, as shown therein closed by a spring pressed valve 32. The at 9, and a spindle lil is rotatably supported in housing I! contains oil and as the piston moves the other end part of the casing 1, the spindle toward the inner end of the cylinder 29, some of 55.

this oil will enterthe cylinder past the valve 32 and then when the piston is moved by rocking movement of the arm 2|, the oil is trapped so that these cylinders and pistons act with the springs to retard swinging movement of. the wheel carrying housing I.

in communication with the interior of the housing l1 and this slot is controlled by a piston 34, the p i i n f whi h an e reeu atedfrom a suitable point adjacent the drivers seat by a connectio '35 so that the driver can increase or decrease the hydraulic control of the pistons and cylinders on the movement of the arm 2|.

A member 36 connects the rear axle ascembly with a cross bar of the chassis A and the ,upper part of the housing I! is connected to a part of the chassis, as shownat 31. v

A plate 38 covers an opening in the housing I for exposing the outer end of the shaft 3, so'that between the wheel spindle and theshaft 3, it will,
